The SVT persists after the initial 1 J/kg shock. Which of the following should you attempt

now?

You are treating a 10-year-old patient after a motor vehicle crash. The patient is unresponsive and flexes his arms at the elbow in response to a painful stimulus. An endotracheal tube is in place with position confirmed. You are ventilating using a resuscitation bag with oxygen, and the child has an SPO2 of 95% and good chest excursion bilaterally. The blood pressure is 130/70 mm Hg, and the heart rate is 90/min with good perfusion. You have established intravenous access. Which of the following actions would be most appropriate at this time?
